Pregnancy announcement on social media. When did you announce your pregnancy? And why?

We plan na magpost pag last trimester na, pag sure na ok na si baby 😍 medyo natrauma kasi ako sa friends ko lately na super updated sa pregnancy nila, todo post nung PT pa lang then eventually nagmiscarry 😔 also less stress din ng onti lang nakakaalam. Immediate family and closest and trustest friends lang may alam so far ❤️
